DISTRIBUTOR.

Application filed August 8, 1924.

Our invention relates to ignition timers or distributors and more particularly to that type of distributor which is combined with a combustion engine and which includes contact mechanism for properly timing and dis-- tributing the sparking impulses to the engine.

A feature of our invention is the provision of means for adjusting the cam portion of the timing mechanism of the distributor whereby the position of the adjusted parts including the cam may be easily locked andY held in their adjusted position to secure a permanent adjustment of the contact controlling means or a cam.

Further features and ad antages of our invention will be more fully described in the accompanying specification and for a better understanding of our invention reference may be had to the accompanying drawing in which a preferred form of our invention is illustrated and in which like reference char acters in the several views denote like parts, and in which:

Fig. 1 is a side elevation of a distributor embodying our invention with some of the elements in section to more clearly illustrate the construction details of the same.

Fig. 2 is a plan view of Fig. 1 with the distributor head and rotor element removed to clearly illustrate the spark timing mechanism.

Fig. is a disassembled perspective view of the elements which are included in the invention.

Referring now more in detail. to our invention as illustrated in the accompanying drawing the device with which our invention is associated may be termed a timer or distributor which is adapted to control the time of occurrence of the distribution of the sparking impulses to the engine and is preferably driven by the engine. The distributor of our invention comprises a cup-shaped enclosing casing EC provided with an integrally formed hub or sleeve provided with a central orifice through which the shaft 2 extends. A member 3 pinned to the shaft 2 forms connecting means between the shaft 2 of the distributor and theengine shaft so as to transmit rotary motion thereto. A plate 4 is secured to the enlarged end of the shaft 2 and carries the pivoted VWeighted members 5 and 6 which in turn are operatively assoeiated with a plate member 'T secured te a Serial No. 730,821.

cam carrying element or stub shaft 8. The cam carrying element or stub shaft 8 together with the plate 11, weighted members 5 and 6, plate member 7 and certain other apparatus not disclosed in the drawing form an automatic control mechanism whereby the cam carrying element S is actuated relative to the engine driven shaft 2 in accordance with the varying speeds of the engine.

The automatic control mechanism that we have referred to is clearly illustrated and described in an application of Louis B. Sauer, Serial No. 708,611, filed April 24, 1024, and for a clearer understanding of the automatic control mechanism with which our invention is associated reference may be had to the above mentioned application.

The stub shaft 8 which adjustably supports the cam 9 is provided with a reduced end portion 10 which rests in an orifice 11 in the shaft 2 and through connection means between the plate 4 secured to the shaft 2 the weighted members 5 and 6 on the plate f1 and the plate 7 secured to the stub shaft 8 motion from the sha-ft 2 which is driven by the engine is transmitted to the stub shaft S. The stub shaft 8 extends through a suitable bearing 12 supported. in a plate member 13 which is secured to the casing EC by suitable screws. The reduced end 14 of the stub shaft 8 protrudes up through the bearing 1Q and adjustably supports the cam 9 and the means for ad justably supporting the cam 9 will now be described. A collar 15 provided with a central orifice 1G of a size to permit it being slipped over the end 111 of the stub shaft S rests against a shoulder 1S formed by an intermediate enlarged portion 19 of the shaft 1S and is pinned to the stub shaft 8 against movement by a pin 20 which passes through suitable orifices 21 in the collar 15 and orifice 22 in the shaft 8. The face 2? of the collar 15 is provided with a straight line nurl which nurling is radially disposed upon the face Q3 with relation to the center of the shaft 8 for purposes as will presently be described.

A washer 2i of soft copper or other suitable material is next slipped over the end 14 of the shaft 8 its face Q5 resting against the nurled face 23 of the collar 15. The cam 9 is provided with a central orifice 26 of a size to permit its being slipped over the reduced end 14 of the shaft 8 and the plurality of lobes 9.7

terrified en its circumferental faire 2S actin shaft, a washer having plain faces interposed between said collar and said cam, gripping means on said collar and said cam, and a locking bolt for associating said gripping means with said washer to maintain said cam in adj usted position.

3. In a device of the character described, the combination with a. driving shaft, a stub shaft operatively related to said first shaft, a removable collar adapted to rest against an enlarged portion of said stub shaft and secured to said stub shaft by means of a pin adapted to extend thru said collar and shaft, said collar being provided with a nurled face, a cam adapted to fit over the end of said stub shaft, a nurled bottom face for said cam, a washer having plain faces interposed between said collar and said cam, and a locking element for associating said nurled faces with said washer to maintain said cam in adjusted position.

4. In a device of the character described, the combination with a driving shaft, a. stub shaft operatively related with said driving shaft, a removable collar adapted to rest against an enlarged portion of said stub shaft and pinned to said stub shaft by a pin adapted to extend thru said collar and shaft, a nurled face on said collar, a cam adapted to fit over the end of said stub shaft, a nurled face 0n said cam, a washer having plain faces interposed between said collar and said cam its said plain faces engaging the nurled faces of said collar and said cam, and a locking bolt for forcing said nurled faces into the faces of said washer to maintain said cam in adjusted position.

5. In a device of the character described, the combination with a driving shaft, a stub shaft operatively related with said driving shaft, a removable collar adapted to rest against an enlarged portion of said stub shaft and pinned to said st ub shaft by a` pin adapted to extend thru said collar and shaft, a nurled face on said collar, a cam adapted to fit over the end of said stub shaft, a nurled face on said cam, a washer having plain faces interposed between the nurled faces of said collar and said cam, and a locking bolt for forcing the said cam and washer down to cause the nui-ling on the said faces to bite into the plain faces of said washer to adjustably maintain the cam in adjusted position.

6. A device of the character described including a cam carrying element comprising a stub shaft, a removable collar having serrations adapted to rest against an enlarged portion of said shaft and secured to said shaft by means of a pin which extends thru said shaft and collar, a cam adapted to fit onto said cam carrying element, a membervhaving fiat faces between the serrations of said cam carrying element and said cam, and means for locking said cam in adjusted position.

7. A device of the character described including a cani carrying element comprising a stub shaft, a removable collar having a surface provided with sei-rations adapted to rest against an enlarged portion of said shaft and secured to said shaft by means of a pin which extends thru said shaft and collar, a` cam adapted to fit onto said element and also having serrations, a flat member of soft material adapted to fit between the serrations of said cam and the scrrations of said cam carrying element, and means for forcing said member into engagement with the serrations of said cam carrying element and said cam for holding said cam in adjusted position.

S. A device of the character described including a cam carrying element provided with an extended shoulder portion, a cam adapted to fit onto said cam carrying element and having the portion nearest the shoulder portion of said cam carrying element serrulated, a removable collar having a serrulated portion, said collar adapted to rest against said shoulder and being secured to said cam carrying element by means of a pin, and friction al means including a member having flat plain faces resting between the said cam and collar and means for forcing said cam and said member down whereby said serrulated portions of said cam and collar are caused to press into the faces of said member for holding said cam in adjusted position.
